Topic: Low Voltage Problem (Read 1293 times)

Yesterday, there wasn't quite a power outage, but the voltage dropped to around 88-100v. Most of my appliances and stuff still worked, but barely. My internet was also down because of this. Also, the low voltage shorted out something in one of my air conditioners and I had to have it repaired. While the voltage was low, my router was on, barely, but no internet. When the voltage finally came back up to normal, I had to call true Internet and have them reset my signal on my router. Just unplugging it and plugging it back in wouldn't do it.

Low voltage is a permanent problem out here. Many people help themselves with "Automatic Voltage Regulators" (AVR). But those don't help when the voltage drops below 150V, which is fairly often the problem around here. So I bought a manual "Step-Up Transformer" for 17,590 Baht at DoHome, that can still work 220V, if power drops to 110V. When my UPS gives its warning signal about low voltage I keep turning the transformer up. Usually it works on 2 or 3, but sometimes I have to turn it up until 6 or 7 (of 9) to keep things working. It gives an acoustic alert, when power goes up again, probably even adjusts or turns off by itself. Since I got that, my power bill went up around 15 - 20%, but things keep working fine, hardly anything broken since then.
